The Senate map is much less fluid, yet this is the time when some races begin to fade in terms of their competitiveness and others become more so. In recent weeks we've seen the New Mexico Senate contest move to the less competitive category, while Connecticut and Indiana are now fully in play. We are still monitoring developments in Connecticut (and could make another ratings change there soon), but new polling in Indiana confirmed for us that a ratings change was due.

California's 21st district: Likely Republican to Safe Republican
This is a district that at one time in the cycle had the potential to be among the state's most competitive. But a series of solid Democratic recruits opted out of running against state Assemblyman David Valadao (R), and the Democrat who emerged from the top-two primary has been underwhelming.

Michigan's 3rd district: Leans Republican to Likely Republican
National parties have yet to even reserve airtime here, which means it's not on their radar. The 1st district remains the only competitive House race in Michigan.

Michigan's 11th district: Leans Republican to Likely Republican
After one of the oddest primaries in recent memory, reindeer rancher Kerry Bentivolio (R) is coasting through the general election against internist Syed Taj (D) in this Republican district.

North Carolina's 8th district: Leans Republican to Likely Republican
Rep. Larry Kissell (D) has always had a difficult path to re-election in a more Republican district (thanks to redistricting). But with recent news that the Democratic Congressional Campaign Committee canceled two weeks of airtime, the window for Kissell to beat Republican nominee Richard Hudson grew a good bit narrower. Republicans have been on the air for weeks pounding Kissell, without any cover from his national Democratic allies.
